It would thus be incredibly unusual for a new appraisal order to go back to the same appraiser. 

I'd work at correcting that through a Ratio Utility Billing Service, but for the purposes of valuing the property now, I'd use at least 50%, and, as another poster said, 60% is not at all unusual.

It's not unusual in older homes to not have air conditioning.

He's telling me that it's unusual to collect last mo. rent upfront and asking if I'd take that requirement away.

You want to know what other types of residential are allowed.It would be unusual for a zoning designation to be single family and yet allow 40 du/a; that density is squarely in the MF zoning density.

Anything that makes a house unusual for its neighborhood is generally going to be a negative.  

Two offers rejected is not unusual. 

We're a bit unusual though- half of our portfolio are Short Term Rentals (where utilities are landlord paid) and most of the other properties are long term rent-by-the-room (where flat-fee utilities are logistically much easier than splitting actual bills).

I know its still quite unusual to find new construction fourplexes here.  

I would estimate 90% of them dont meet reserve at auction and thus dont sell that week, they re-auction the following week, this can go on for many months, two to three is not unusual in our area I have seen them up to five month, takes a lot of patience, but every once in a while we snag a good one.
